Abstract

The lamp has a reflector (2), which surrounds the light element (4). The light element is installed in the intermediate ceiling (8). A passage (9) is provided between the reflector and the light element in the upper part of the lamp, which is turned to the socket. Air can be exchanged between the area defined by the reflector and the area, which surrounds the reflector. An Independent claim is also provided for a reflector.
